A new permanent magnet design of quasi-axisymmetric stellarator was made by researchers led by Prof. Xu Guosheng from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of ...

Compared with the traditional gear box, the permanent magnet speed regulator, which is based on the magnetic eddy due to the relative motion between the permanent magnet and the conductor, has several ...

Electro-permanent magnets (EPMs) are pretty nifty concepts, and if you aren’t familiar with them, they are permanent magnets with the ability to be electrically switched on or off. Unlike an ...

It was a moment three years in the making, based on intensive research and design work: On Sept. 5, for the first time, a large high-temperature superconducting electromagnet was ramped up to a field ...

Interior rotor brushless DC motors (BLDCMs) are lightweight, compact, and efficient, offering high torque over a wide speed range, which makes them well suited for electric vehicle (EV) applications.

A nuclear fusion experiment at the University of Wisconsin-Madison has set a record for the strongest steady magnetic field confining a plasma, ushering in new hope that forthcoming demonstration ...

Magnetic couplings transmit high torque with no physical contact, and they disengage smoothly when load gets too high. Generally speaking, the couplings use magnetic power in three different ways; ...
